To catch fine particles before they get to the filter, try putting a skimmer sock (pool store or WalMart, pkg of 3 for about $5) or regular panty hose over skimmer basket. This will catch quite a bit of gunk, and will need to be rinsed off several times a day while you're battling the 'Lake Effect'.

You'll definitely need to raise your chlorine level to at least 15ppm (depending on your CYA levels) and hold it there until water clears. Filter 24/7, clean cartidges as needed.

Post chemical numbers, and if necessary, get water tested at pool store. But don't let them talk you into buying anything.

Good luck.
